I'm working on Windoze XP and have for some time installed R in D:\R and upgraded my packages after installing the new version of R with a bit of code I think I got from the list: ip <- installed.packages(lib.loc = "d:\\R\\R-2.4.1\\library") ip <- ip[ip[,1]!="base" ,1] install.packages(ip) This time around that's produced some warning grumbles: Warning messages:

Dear all, My gRbase package imports functionality from the bioconductor packages graph, Rgraphviz and RBGL. To make installation of gRbase easy, I would like to have these bioconductor packages installed in connection with installation of gRbase, but to do so the user must use setRepositories() to make sure that R also installs packages from bioconductor. Having to call setRepositories causes

Hey, all. I'm looking for packages that are good at two things 1) Drawing directed graphs (i.e nodes and edges), both with single and double headed arrows, as well as allowing for differences in line width and solid versus dashed. Note: I've tried Rgraphviz here, but have run into some problems (which seem fixable and I may go with it in the end), and it doesn't satisfy need

Full_Name: Christian Kuehnert Version: 2.7.1 OS: Windows XP Submission from: (NULL) (91.14.237.109) Hello, I've installed the package RBGL (and XML and Rgraphviz) and tried to follow the examples in the RBGL-manual http://bioconductor.org/packages/2.2/bioc/vignettes/RBGL/inst/doc/RBGL.pdf But when I try to plot the graph using e.g. plot(dijk) an error message occurs: "Error in

Dear R-users, I'm finding for a R-package concerning graphs. Is there some kind of that package? I've a set of correlation coeffients between several variable and I wish to built a graph to link variables correlated. Many thanks.

Good morning, i'm drawing a barplot (data are stored in a matrix,nrow=3,ncol=10). So i get 10 groups each containing 3 sub-bars. I need to change the range of the y-axis when i plot respectively the first and the other two sub-bars in each group. I can't manage. Could you help me? Thank you. Angela

Hello there, I am using the igraph package to build graphs from my data. If I plot a graph though, it's not easy for me to see what's going on. Does anybody know how to rearrange a graph to get a plot without too many crossing lines? Maybe other packages? Thanks a lot in advance for any pointers, -- D --------------------------------- [[alternative

Dear all; I would like to draw a graph with vertices and edges, and I guess tcl/tk would be appropriate. I don't know tcl/tk but have googled for a 10-page (or so) introduction to 'getting started with tcl/tk in R' but without any luck. - Does anyone know of the existence of such a document or any other web-based material on the subject? - Does anyone have an (informative) piece of

Hi all, When installing ggplot2 on with install.packages("ggplot2", dep = T), the colorspace dependency doesn't get installed (see below for transcript from R session). The relevant lines from my description file are: Depends: R (>= 2.4), grid, reshape (>= 0.8.0), proto, splines, MASS, RColorBrewer, colorspace Suggests: quantreg, Hmisc, mapproj, maps Have I done something

Dear R users, I'm using graph library to create a mesh-like network topology and implement a load balance routing algorithm. The current implementation uses graph, RBGL, and Rgraphviz libraries. I have a few attributes on every edge to represent the network loading and capacity, and I frequently update these values. However, I found it works so slow and right now I'm consider rewriting it

Hello, I apologise if someone has already answered this but I searched and googled but didn't find anything. I have a matrix which gives me the similarity of each item to each other. I would like to turn this matrix into something like what they have in the graph package with the nodes and edges. http://cran.r-project.org/doc/packages/graph.pdf . However I cannot find a method to

I have developed a problem with the postscript output of plot on Windows. My code still works properly with R 2.3 but, with R 2.4, the white text on red background does not show up. It does, however, show up when output is sent to the screen. Below is my code and sessionInfo.

Hi all, I am rather new to R. Recently I have been trying to implement some tree algorithms in R. I used lists to model tree nodes. I thought something like this would work: parent <- list(); child <- list(); parent$child1 <- child; child$parent <- parent; When I tried to check whether a node is its parent's first child using "if

Documentation on how to put classes and methods in packages with namespace? How should I define my classes and methods in "dynamicGraph"??? (That is - Can some one point me to the documentation on how to put classes and methods in packages with a namespace? ) Currently it is done by the code below. This gives problems, when a workspace with a "dynmaicGraph" is

Re. the Kings Quest game called R, Inspired by the "stats4" of R-1.9.0 (alpha of 2004-03-15) I moved the body af my function ".onLoad.dynamicGraph" to the end of ".../dynamicGraph/R/dynamicGraph" (replacing "library(methods)" by "require(methods)"). The secound run, with [Previously saved workspace restored], produces the same result as in

I have recently upgraded to Ubuntu Gutsy and, for the first time, am using a 64-bit installation. After failing miserably to install R from source, not a problem for me in the past with a 32-bit install, I went the route of using the Debian Etch build. This went smoothly, but I am unable to update my numerous R and BioConductor packages, getting non-zero exit status errors on each package. Is

Good afternoon, I'd like to know how to superimpose a Student distribution pt on a histogram. I think I have to use the plot function but I don,t know the details. Other question: what is a quntile function? Can you help me? Thank you.

Hi, I am approximation a value function (in dynamic programming) V: R^n->R. In different versions of the problem, n is between 2 and 5. I would like to use splines to use this, I checked the mailing list and CRAN but couldn't find anything that would help me (Tps in fields is too slow, cobs would be really nice but seems to be one-dimensional). Is there any package that would at least
